I’m a consultant and seminar leader who specializes in the graphical display of data. I train employees of corporations and organizations on effective data visualization. I also review documents and presentations for clients, suggesting improvements or alternative presentations as appropriate. I’m the author of Creating More Effective Graphs, published by Chart House in 2013 (reprinted from Wiley 2005). In addition to my one and two day seminars on creating more effective graphs, I offer short programs such as “Recognizing Misleading and Deceptive Graphs” and “How to Avoid Common Graphical Mistakes.” I received a Ph.D. in mathematical statistics from Columbia University, M.A. from Cornell University, and A.B. from Bryn Mawr College. I had a long career at Bell Laboratories before forming NBR, my consulting practice.

Looking Back on My First Year of Blogging

It’s hard to believe that I have completed my first year of blogging. I’ve been posting approximately once a week and this is my 53rd post. It’s a good time to see where we’ve been and decide where we should be going.

I just categorized the posts to date. The categories I used are methods, principles, criticisms, tables, announcements, and miscellaneous. These categories are not mutually exclusive and many of the posts could have been placed in a different category. I frequently criticized a graph form such as multiple pie charts and then showed an alternative presentation of the data such as in Arrow Charts and Other Alternatives to Multiple Pie Charts. I placed that post in methods since it was intended to show an alternative to many pairs of pie charts rather than criticizing a specific chart. Figure 1 shows the number of posts in each category.
